We think so, in the form of an allowlist that allows trading between normal wallets (also known as externally owned accounts or EOAs) and specifically allows marketplaces that respect royalties.

Unlike deny lists, which enumerate wallets and smart contracts that are specifically banned from transferring an NFT, allow lists only allow good actors to participate, avoiding a number of problems. Prime among them is that using a deny list would inevitably result in a game of whack-a-mole, where new marketplaces would get deployed continuously to avoid paying creator fees.
